Fitting
Removal of Handle
Before fitting the valve, make sure that the pipe
system is clean and:
1. The valve can be turned 360 degrees, if
threaded pipe is used.

50 122/67
1. A screw becomes accessible when the cover
cap is removed.
2. Loosen the screw and remove the handle.
3. When mounting the handle, valve and handle should fit together. Turn the handle until
notch, and the handle will drop smoothly on
the valve.
Open and Close
Draining - High Capacity
Valve can be closed turning the handle in two directions.
Handle align with the valve = Open valve (1)
Handle across the valve = Closed valve (2)
Possible drain through the valve using a 6 mm
hexagon key. When handle is closed drain follows
from the side where the drain is placed.
Drain cock has ¾” thread.
